PLANE.

SPECIFICATION forming part of Letters Patent No. 766,473, dated August2, 1904.

Application filed January 7, 1904. Serial No. 188,049. (No model.)

To all whom ff may concern:

Be it known that I, JUs'rUs A. TRAUT, a citi- '/.en of the UnitedStates, residing at New Britain, in the county of Hartford, State ofConnecticut, have invented certain new and useful Improvements inPlanes, of which the following is a full, clear, and exact description.

My invention relates to improvements in planes.

IO The object of the invention is to provide a plane of a simple andreliable construction which maybe employed in the usual manner orreversed, as in double-ended planes, and adjusted to vary the cuttingdepth of the 5 plane-iron.

The invention consists in employing, in a plane-body having two throatsor openings, one in the plane near the front end and the other near theopposite or rear end, a pivoted step or yoke midway between two inclinedguideways, with which coacts an adjustingscrew, one portion of the screwcoacting with a block slidable upon either one of the inclined guides toadjust the plane-iron.

5 Details of the improvement will be more plainly seen on an inspectionof the accomianying single sheet of drawings, in which Figure 1 is aside elevation of a plane embodying the improvements of my invention.

3 Fig. 2 is a longitudinal section of the same, the front handle being,however, broken away and the operating parts shown in position with theplane-iron at the front opening or throat. Fig. 3 is a longitudinalsection of a plane embodying my improvement with the parts reversed,showing the plane-iron adjusted through the rear throat or opening, Fig.& is a plan view of my improved plane, the parts beingshown in theposition of Fig. 2.

4 Fig. 5 is a cross-sectional view of the plane taken through thepivotal screw step, the plane-iron and adjusting-screwbeingremoved,showing the step hanging down in the position which it occupies whenthese parts are removed. Fig. 6 is a cross-sectional view of theadjusting-block through which the adyustingscrew passes and which servesto extend or retract the plane-iron.

1 indicates the body of the plane.

2 is the throat toward the forward end of 5 the plane through which theplane-iron is adapted to project, and 3 is the throat near the rear endof the plane-body.

L is a plane-iron of suitable construction.

5 is the plane-iron cap for holding the planeiron securely in place. Inthe form of my invention herein shown this plane-iron cap terminates atthe upper end in a handle portion 6.

7 is a clamping-lever of suitable coustruction.

8 and 9 are screws which take into the posts 10 and 11, respectively,and for the purpose of coacting with the plane-iron cap for holding itin place. 5

12 and 13 are oppositely-inclined ways at the rear and front of theplane, respectively, which afl'ord guides for the adjusting-block 14.

15 and 16 are projections from the block 14, adapted to coact withrecesses in the rear 7 of the plane-iron 4.

17 is a thumb-nut for operating the adjusting-screw. The threadedportion 18 of the screw coacts with the adjusting-block 11.

19 is a step for the adjusting-screw in the form of a yoke which has ascrew-threaded portion to correspond with the screw-threads 20 on theadjusting-screw. It will be noted that the pitch of the screw 20 isgreater than the pitch of the screw 18. In this instance it is exactlytwice, in order that when the thumbnut 13 is turned in one direction orthe other the adjusting-block 1% may move correspondingly as theresultant of the difference between the pitchcs of the screws. 5

21 and 22 are pivot-pins for the step 19, which pass through the lugs 23and 2 1, which are preferably cast integral with the body of the planeon either side.

25 and 26 are small grooves cut in the up- 9 per surface of the base ofthe plane to allow slight clearance for the lower end of theadjusting-screw when it is being operated and reversed. Ordinarily theplane is used with the parts in the position as shown in Figs. 1, 2, anda. When, however, it is desired to use the plane in a corner or someother position, the parts may be reversed, as shown .in Fig 3. Toreverse the parts, the cap 5 and the iron 4: are removed after releasingthe lever 7, When the adjusting-screw and adjusting block and step maybe swung over to the position shown in Fig. 3, the parts pivoting on theaxis of the pins 21 and 22. In this position the parts may be againassembled, as shown in Fig. 3, when the plane 'will operate as before.

I The construction will be seen to be simple and not at all likely tobecome injured or disarranged accidentally, and yet the reversal oradjustment of the parts in either of their positions may be'eifeetedwithout difliculty.

What I claim is 1. In a plane in combination a body portion, having twothroats, a plane-iron, a pivoted step, an adjusting-block, anadjustingscrew coacting with said block and said step andoppositely-inclined guideways forming supports for said adjusting-block.

2. I In a plane, a body portion having a plurality of throats, aplane-iron, acap, inclined guideways and cap-screws for said iron towardeach of said throats, clamping means,

and reversible means for manually adjusting the cutting depth of saidplane-iron through either of said throats.

3. In a plane, a body portion having two throats, a plane-iron, a cap,cap-screws and a clamp for supporting said iron in position at eitherthroat, and reversible adjusting means coacting with said iron in eitherposition for varying its cutting depth.

4. In a plane, a body having two throats, a plane-iron, a cap,capscrews, a clamping-lever and a reversible adjusting-block and meansfor moving said block to adjust the plane-iron through either throat asmay be desired.
